USB-UIRT and lirc-0.8.2pre*

[Pieter G <pie...@gm...>]

Hi,

I have purchased an USB-UIRT module about a year ago and had no
success with this otherwise cute hardware. (T00038 38kHz version as
per months worth of searching)

I have tried various versions of the lircd0.7 range to the latest CVS
snapshot on both Suse9.3 and Suse10.1

I get the following output from lircd -n --device=/dev/ttyUSB0 :

(one instance)
./lircd -n --device=/dev/ttyUSB0
lircd: lircd(usb_uirt_raw) ready
lircd: accepted new client on /dev/lircd
lircd: uirt2_raw: checksum error
lircd: uirt2_raw: UIRT version 0905 ok
lircd: error processing command: SEND_ONCE remotename 3
lircd: transmission failed
lircd: removed client
lircd: accepted new client on /dev/lircd
lircd: uirt2_raw: checksum error
lircd: uirt2_raw: UIRT version 0905 ok
lircd: error processing command: SEND_ONCE remotename 3
lircd: transmission failed
lircd: removed client

And in other cases:

lircd: uirt2_raw: checksum error
lircd: uirt2_raw: detection of uirt2 failed
lircd: uirt2: trying new uirt firmware
lircd: 23 dd
lircd: 09 05 01 01 1a 03 04 cf
lircd: uirt2_raw: UIRT version 0905 ok
lircd: 21 df
lircd: 21
lircd: error parsing command :SEND_ONCE ...... etc

lsmod and modules checks out OK:

May  4 06:46:35 linux /etc/hotplug.d/ttyUSB0/50-visor.hotplug[14204]:

Now my questions:

Can the problem be with the  ftdi_sio modules? That is the stock 10.1
module as well as stock on the 9.3 installation?

I have the iMON IR receiver in my box and lirc captured some remote
waveforms just fine. But when I try to irrecord on the UIRT interface
it complains about something went wrong. (The light flashes when I
point a remote at it, and have pointed about 4 different remotes at
it)

Can the transmit errors I see on lircd be because I use iMON captured
lircd.conf entries on the USBUIRT lircd?

Is the problems I have ftdi_sio module problems (hence causing the
checksum errors) or something I keep on missing with LIRC?

I have in desperation built the IR homebrew transmitter as well and
<sigh> my HTPC's serial port is burnt-out. So I tried using a
USB-to-serial converter with this homebrew IR transmitter.

The device is also created as /dev/ttyUSB0 and it works (can see the
LED on that converter flash and data does go through in other
configtests). But LIRC does not seem to like it.

Any suggestions on a LIRC+(USB-to-serial)+HomeBrewIRTransmitter?

My apologies for the VERY long submission. I know you guys are busy coding!

Your help is appreciated!
